Yes, that was sloppy of me. You have to be precise when talking about the effects of biological evolution on our brains. We know our brains were initially created entirely by biological evolution; what's not clear is how direct or indirect the influence of evolution has been on our psychology. That is, does evolution hardwire relatively complex behaviour (as it does in many animals) or does it merely specify high-level learning algorithms? This appears to be the case with humans - we don't have many instinctual behaviours compared with other animals, but we do have an instinctual ability to learn new things. It's interesting to speculate how this ability might have arisen; the ability to learn new things and to spot patterns must have been useful to our distant ancestors, as they're such fundamental traits of human cognition. This is also why the "nature vs nurture"/"biology vs culture" debate is a false dichotomy: the foundation of human culture is our ability to learn, which is itself a genetic adaptation.
